Apart from domestic services, Royal Mail is also well-equipped with international postal services. It does an excellent job delivering mail items to over 230 countries. So, if you live in the US, you can easily receive mail from the UK via Royal Mail.

However, the time frame to deliver international mail is much longer than delivering domestic mail. So, you have to be a little patient. But, again, there are specific options that help you get your mail faster.

But… wait!

What are these options? How long does Royal Mail take to the USA? What is the fastest Royal Mail delivery?

In this blog, we will cover everything you need to know about Royal Mail. Also, we will discuss the answers to the above questions to give you a better idea about the workings of this organization.

What Is Royal Mail?

Let us start with knowing what is the UK postal service. As we said above, Royal Mail is the prime postal service provider in the UK. It offers mail delivery and collection services through its post offices.

Every year, Royal Mail delivers billions of letters and parcels. Hence, you can imagine the number of people working with Royal Mail and the huge chain that it has created across the country.

As of 2019, there were 162,000 permanent workers employed with Royal Mail. Also, around 18,000 more workers were employed temporarily during November and December to handle Christmas mail as the demand increased massively during the holidays.

Royal Mail has several mailing options for sending mail within the UK. But, its international mailing options are no less. You can avail of these options for reasonable prices compared to other courier companies that charge a lot more.

To send something, you can drop your letters and parcels in a post or parcel box. If you own a business, you can request your local post office for regular pickups. These mail items are then taken to the Royal Mail sorting offices and further sent for delivery.

The Rich History of Royal Mail

The British mail service first came into existence in the year 1516 as Royal Mail Group plc. Royal Mail Group Limited is a subsidiary of Royal Mail Group plc.

With time, the Royal Mail Group developed two brands, namely Royal Mail (for letters) and Parcelforce Worldwide (for parcels).

It all started in 1516 when Henry VIII assigned the ‘Master of the Posts’ position to someone. This position was created and appointed by him to manage the incoming and outgoing mail in the country. Later, in 1710, this position was renamed as ‘Postmaster General’ as we know it today.

This event was the first significant milestone in the establishment of the Royal Mail. Another vital highlight is the introduction of postal stamps—a concept that was later adopted by the whole world.

The first-ever stamp called the ‘The Penny Black’ came into use in 1837. Following the Royal Mail’s footsteps, France also adopted the concept of postage stamps in the next decade.

Like other postal organizations, Royal Mail too was under the control of the government for hundreds of years. But, things began to change in 2006 when the government opened the postal market for competition, leading to the end of a 350-year British Empire monopoly.

In 2013, the British government listed most of its corporate shares on the stock market. Two years later, it also sold the remaining shares making Royal Mail a publicly owned company.

This way, centuries of government ownership over postal services saw an end. Now, UK citizens enjoy the services of a modern company that offers far better services than a crown corporation.

Now that you know what is the Royal Mail, let’s move ahead and learn about its functioning!

Royal Mail Address Format and Guidelines to Use This Service

This section is beneficial as it tells you how to format a mailing address according to UK standards.

Please find the Royal Mail address format below:

Recipient’s name
House/unit number and street address
Locality name
Postcode (print or write in capital letters)

Recipient’s name: It is best to use the person’s full name with an appropriate title, like ‘Dr’ or ‘Cptn.’ This line should always come above the mailing address. Refrain from writing the recipient’s name anywhere else on the envelope.

Suppose you are mailing something to an organization. In that case, you can add the organization name on the second line, below the person’s name, followed by the below-mentioned:

House/unit number with street address: These two aspects of your mailing address should always be on the same line. Take care to add directionals to your street addresses whenever needed.

Locality name: You can skip this line if you can. However, if you do use this line, write the correct village or area name.

Town: Write the town name in capital letters. This line should not have anything else other than the town.

Postcode: Again, the postcode should be written or printed in uppercase letters. Make sure to leave a space in between.

Find an example of a UK address below:

Miss Jane Holland
5 Castle Street
L16 5NT

Find some additional tips below to write a UK mailing address correctly:

  • Write the name and address on the bottom-left corner (frontside) of your envelope or parcel.
  • Mention the return address on the bottom-right corner (back side) of your mail.
  • Use legible handwriting or print the mailing address.
  • Leave enough white space around the address.
  • Place your postage towards the top right on the front side.
  • Avoid using commas and full stops.

You don’t need to add the country name for domestic mail items. However, the format is a little different for mail going to the US.

The format for writing a US address is as follows:

Mr. Joyce King
036 Krog Street

It is preferred to add ZIP+4 codes, though 5-digit ZIP codes are also acceptable. Also, you can write the abbreviation USA instead of the whole thing.

Postal Codes in the UK

As compared to ZIP codes, postal codes in the UK are a bit complicated. They work in almost the same way, but there are some minor differences.

For starters, ZIP codes are a coding system used by the USPS to identify the mail destination and speed up the delivery process. On the contrary, postal codes help track the mail location.

Also, ZIP codes are numeric, and UK postal codes are alphanumeric, making them more similar to Canadian postal codes.

Now, UK postal codes are called postcodes. They are six to eight characters long (including a space) and have two sections—outward code and inward code.

The outward code forms the first part and typically has three to four characters. In contrast, the inward code always has only three characters.

There are four parts hidden inside these two sections:

  1. Postcode area
  2. Postcode district
  3. Postcode sector
  4. Postcode unit

The postcode area denotes a geographical location divided into postal districts. Furthermore, postal sectors are subdivisions of postal districts, and postcode units are subdivisions of postal sectors.

Hence, postcodes are all about narrowing down the mail destination while also describing the entire location at large. 

To understand postcodes better, let’s take an example:


Outward code Inward code
Area District Sector Unit
AB 1 9 TH

Outward Code

The outward code is two to four characters long and consists of the postal area and district. As said above, it indicates a prominent geographical location and is often the city code. For example, the postcode area ‘B’ is for Birmingham, ‘EH’ is for Edinburgh, and ‘AB’ is for Aberdeen.

Outward codes consist of:

Postcode area: In our example, the postcode area is AB which indicates the city of Aberdeen. Postcode areas are either one or two characters long and often correspond with city names.

Postcode district: The length of postcode districts is also between one to two characters, and the second character is sometimes an alphabet. In the above example, the digit ‘1’ is the postal district.

Inward Code

The inward code is always three characters long and follows the digit-letter-letter format. Its components are:

Postcode sector: This one is tricky! The postcode sector is the entire outward code, the space, and the first digit of the inward code. So, in this example, it is AB1 9.

Postcode unit: The last two letters of the inward code are the postcode unit (TH). These characters are like ZIP+4 codes that indicate delivery routes. They could either correspond to an entire street to small sub-sections of large buildings. Sometimes, businesses receiving a massive volume of mail get unique postcode units.

We understand that postcodes can be confusing. So, use the Royal Mail postcode finder here to confirm postcodes before writing them on your mail.

Post Offices and PO Boxes in the UK

There are 11,500 post office branches spread across the UK. So, you are likely to have a post office nearby that you can visit during working hours.

Some of these are standalone stores, whereas others are part of certain retail outlets like WH Smith. You can recognize post offices in the UK by red oval signs.

Larger post offices have machines that allow you to calculate and print postage yourself. Such self-service machines can help speed up the work and attract lesser crowds.

But, if you are planning to visit smaller post offices or the ones inside a retail outlet, it is advisable to avoid peak hours.

Apart from mailing letters and parcels, you can also find a range of other postal services at UK post offices. Some additional services that specific post offices offer are:

  • Banking and financial services like mortgages, insurance products, personal loans, and savings accounts. 
  • Home internet services.
  • International money transfer via Western Union.
  • In-house currency exchange.

Please remember that the scope of these services differs from branch to branch. 

Along with post offices, there are also several PO Boxes. By several we mean, there are 115,000 post office boxes in the UK

If you want to keep your mailing address private, you can consider using PO boxes. It is also an excellent option for home-based businesses and individuals that have shared accommodation.

What is the Royal Mail PAF File?

PAF stands for the Postcode Address File and has over 31.437 million postal addresses and 1.79 million postcodes.

This file lets Royal Mail deliver your mailers to accurate mailing addresses, reducing errors, misplacements, and lost items.

It regularly updates this file to filter outdated data and add new mailing addresses. The PAF database also allows the Post Office to keep tabs on people who recently shifted to a different location. 

Individuals and businesses can update their new mailing addresses with the Post Office to redirect their mailers and avoid losing mail. 

These new addresses reflect in the PAF database, allowing mail senders to ensure their items reach the correct people. 

PostGrid’s direct mail API helps you mail to addresses in the PAF file. Our address verification feature allows you to standardize and verify your mailing lists according to this authorized database, ensuring on-time deliveries and reduced mail returns.

What Is Royal Mail Tracking Number?

After discussing so much about tracking options, you may wonder things like ‘how do I track my Royal Mail International?’

It is easy to track your mail items through the Track and Trace service. But, make sure that your items are eligible for tracking.

Click here and enter your reference number to track your mail. You get a reference number at the time of posting. It is also often known as the tracking number.

How many digits is a Royal Mail tracking number?

Most of the time, a tracking number is alphanumeric and has nine digits. However, several other tracking number formats also exist. 

The different tracking number formats that you are likely to come across are:

UK Tracking

  • Two alphabets and seven digits (for example, HJ8931576)
  • Four alphabets and ten numbers (for example, BBBB0000000000).

The tracking number and its format depends on where your mail is going.

International Tracking (Exports)

  • Two alphabets and nine digits followed by the alphabets GB (for example, NK035789165GB)
  • 12 numbers (for example, 123456789079)

So, if you send something to the US or any international location, expect your tracking number to look like this. 

International Tracking (Imports)

  • Two alphabets followed by nine digits and again two alphabets (for example, AA987654321AA)

You can find the tracking number on your receipt or the mail item’s label. If it’s on the label, note down this number before you continue mailing the item. 

It is your responsibility to keep your receipt safe. Once it is lost or torn, getting the number again to track your item is tough. 

Also, please note that no other information like the address and recipient name can help you track your items.

Reasons Why Your Tracking Number Is Not Working

Sometimes, your Royal Mail to USA tracking does not work due to some reasons, and they are:

  • It has only been a day since you posted your item. The Royal Mail tracking system needs some time to get your tracking number up and running.
  • You may have entered an incorrect tracking number on the website.
  • If you are the receiver, maybe the sender sent you an incorrect or invalid reference number.
  • The option you selected for mailing does not have a tracking feature.

In any of the above cases, the Track and Trace website won’t return any results. So, be patient and enter the correct tracking number to get your mail status.

Reasons for Royal Mail Late Deliveries

Now that you know the days when Royal Mail does not deliver mail, you must also understand there might be delays on other days because of uncontrollable factors.

Here are some of the primary reasons the Post Offices fail to deliver on the estimated arrival date:

Unprecedented Demand Surge

The postal services might face an unexpected demand surge before the weekend or at other times. This situation can lead to many delays, pushing your arrival dates ahead.

It is vital to check your tracking updates and the Royal Mail website to learn about these factors and prepare to face the issue.

Please note that Royal Mail does its best to handle these scenarios by hiring part-time and temporary staff to ensure the mail reaches the destinations on time.

Holiday Season

You might face delivery delays during Thanksgiving, Easter, Christmas, and New Year’s Day.

Almost all individuals and businesses mail during the holiday season. Thus, Royal Mail gets more items to deliver than usual, creating a chaotic environment.

Though it prepares to handle the increasing volume of mailers, it is easy for things to get out of hand.

The trick is to use Special Delivery Guaranteed services or mail in advance to guarantee the Post Office prioritizes delivering your mailers.

Or use PostGrid’s direct mail API to plan and execute the campaign quickly. Since you don’t do anything in-house, you can ensure your mailers are out of the door in advance.

Road Accidents

Highway construction, road accidents, jammed roads, and other similar issues are out of the control of the Post Office. Thus, it may temporarily suspend services in some areas, delaying mail deliveries.

Try staying updated about these events before mailing something to seek alternative options or shipping the mailers after the situation improves.

Extreme Weather Conditions

Extreme snowfall, rainfall, and other weather conditions can compel Royal Mail to delay deliveries. It cannot risk the lives of its delivery staff by asking them to drive in such situations.

Also, reaching some rural locations with challenging weather conditions can take longer than the Post Office anticipates.

Lack of Delivery Carriers

Royal Mail UK employs adequate personnel to complete deliveries. But sometimes, a lack of carriers can cause delays.

Again, it is an uncontrollable situation, like when many employees are on leave or quit simultaneously.

Please wait one to two business days before lodging an official complaint, as it gives the Post Office some time to resolve the issue.

Mailing After the Cut-Off Times

One of the reasons Royal Mail cannot deliver your items on time is posting them after the cut-off time.

The Post Office shifts your delivery date to another day if you fail to drop off your items in the mailbox or take them to the Post Office before the closing hour.

Please remember that every Post Office may have different timings. It is best to stay informed about the working hours and post items before cut-off times.

For instance, imagine you drop off something at the Post Office on Friday evening. What happens if this postal outlet remains closed on Saturdays and Sundays?

Yes. Royal Mail considers that you dropped off the items on the next working day—Monday! Hence, you may think it has delayed your mail delivery, but it initiated the process late because of the cut-off time.

Incorrect Mailing Addresses

Mentioning incorrect mailing addresses on your envelopes or parcels can cause delays, irrespective of your selected delivery option.

Even minor errors, like typos or spelling issues, can disrupt the mailings.

The Post Office may need to hand-sort your items before shipping. Or your mailers may get stuck during the last-mile delivery from the final postal outlet to the recipient’s address because of confusion or misinterpretation.

Postal service will lose mail that has the incorrect address.

Not Following the Postal Mail Guidelines

Royal Mail has specific size and weight requirements senders must follow.

It is best to learn and follow these guidelines before mailing to avoid potential issues, like the postal services returning the items to your address.

Fortunately, PostGrid helps you comply with the postal guidelines and ensure timely deliveries.

Our PDN (Print Delivery Network) does its best to prepare and distribute your mailers under postal regulations.

Thus, you need not worry about whether you can follow the rules because you don’t need to do anything in-house.

PostGrid lets you execute successful mailing campaigns via Royal Mail without going anywhere, finding separate vendors for every task, or putting in any effort.

Undelivered Mail Items

Why does Royal Mail fail to deliver some items? Perhaps, we can list all the possible reasons:

  • Part of the mailing address was missing, or you didn't write it correctly. Use PostGrid’s address verification API to avoid such issues.
  • The address no longer exists (for example, the building is under reconstruction).
  • Insecure packaging wherein the address label comes off.
  • The postage is unpaid. 
  • There was no one to receive the mail (Royal Mail Signed), or the mail was too big for the letterbox.
  • The recipient refused to accept the mail.
  • A security system at the address stopped the postal worker from gaining access to the recipient.
  • If access to the delivery address is unsafe or impossible, the recipient is called and asked to collect their mail.
  • The items you sent are either restricted or prohibited. 

So, before thinking about how long does Royal Mail takes from the UK to the USA, make sure you don’t want to mail any of the prohibited items. 

Royal Mail Prohibited and Restricted Items
