  • The tool standardizes all the addresses according to the local country format.
  • It parses the addresses into its components using lexicons and rules.
  • It checks and informs you about the delivery status of each address separately.

PostGrid For Address Correction: Fuzzy Error Prevention

At PostGrid, our intelligent fuzzy matching capability is the best on the market. We correct misspellings, complete abbreviations, and fill in the missing information. Below is what we deal with:

  • Spelling Errors: Our address verification tool can understand what you meant to write even if you do not know the spelling of words or accidentally hit the wrong key. Additionally, this can be extremely useful for internal systems where addresses are taken over the phone and spelled differently than the way they sound.
  • Switched or Misplaced Words: Typists are notorious for switching adjacent letters in words, as in Raod (Road) and Mian (Main). This is detected by our tool, and we can help you understand what your user wants. PostGrid’s address validation service will help you find your address even with missing words and letters.
  • Abbreviations or Nicknames: Our Restful API can even identify the correct address if words are shortened, using abbreviations – such as Blvd for Boulevard, or if you use familiar, regional names, even if the suburb has been absorbed into the city’s jurisdiction.
  • Dealing with Extra Space: Street names and places can be confusing because they can be made of one or two words, or maybe they’re hyphenated. Despite unclear spacing or accidental additions of too many spaces between words, our address correction or verification API locates the address.

PostGrid: Our Workings to Correct Address

We also help you validate incoming postal addresses in real-time using our API. Occasionally, customers forget to enter their apartment number or misspell their street name.

When you integrate address verification API, our servers check the customer’s information against the US Postal Service’s or the Canadian Postal Service’s database. The user will be prompted to try again if the information is incomplete or inaccurate. By doing so, you will be able to effectively move packages since you will only accept valid contact credentials.

Our checkpoints are as below:

  • PostGrid’s address checker can successfully verify both US and Canadian postal addresses in real-time or via batch upload
  • We have an intuitive platform that automatically corrects a minor misspelling when it is made and does not interrupt the end-user
  • By simply collecting the street address and zip code, you can speed up the registration process. The city and state data will automatically fill in
