LoadingAccuracy Type
One of the following values:
- Rooftop, indicating that the exact point was found
- Point indicating that the exact point was found within a range of addresses
- Range_interpolation indicating that we used interpolation to generate the result (still fairly accurate)
- Nearest_rooftop_match, indicating we found a nearby rooftop point and used that
- Intersection, indicating we found a street intersection at the point
- Street_center indicating we used the center of the closest street
- Place indicating that the point was a city/town/place
- State indicating that the point was just a state
How Does Geocoding API Work?
Reach out to the PostGrid support team to request geocoding activation on your existing account. No new signup required.
Our team enables the geocoding add-on on your account and confirms your API key is authorized to return coordinate data.
Add geocode=true as a query parameter to any existing verification POST request. No new endpoint needed.
PostGrid validates the address against USPS CASS and Canada Post SERP records, then returns a geocodeResult with precise lat/lng.
Feed geocode data into your routing engine, CRM, or mapping platform for last-mile delivery, analytics, or location services.
Geocoding API Features Your Platform Needs
Secure precise location data backed by verified, postal-certified address records
01
Global Coverage
Access verified geocode data for addresses across 245+ countries and territories with consistent international address formatting.
02
CASS & SERP Certified
Every geocoded address is validated against official USPS and Canada Post records before coordinates are returned, ensuring per-address deliverability.
03
Forward Geocoding
Convert any mailing address into exact latitude and longitude coordinates. Returned in every verification response when geocode=true is set.
04
Accuracy Scoring
Every geocode result includes an accuracy score (0.00–1.00) and accuracy type: rooftop, range interpolation, street center, and more for precision.
05
Bulk Geocoding
Upload address lists via CSV to receive coordinate data in a batch. Designed for large-scale database enrichment.
06
NCOA Integration
Cross-reference addresses with USPS National Change of Address data before geocoding, ensuring coordinates always reflect the most current, deliverable location.
07
Sub-Premise Accuracy
Go beyond street level and retrieve coordinates pinpointed to specific apartment, suite, or unit addresses for precise last-mile delivery targeting.
08
Timezone & Census Data
Pair geocoding with includeDetails=true to receive timezone, US Census tract, congressional district, carrier route, and residential/vacant flags alongside coordinates.
09
ZIP+4 Lookup
Append the extra four digits to ZIP codes for the highest level of postal routing accuracy before geocoding is applied to the verified address.
10
DPV Confirmation
Perform real-time Delivery Point Validation as part of the same request before geocoding to confirm every address is physically serviceable by the post office.
11
Native Integrations
Connect geocoding data with 1,600+ apps via Zapier, including HubSpot, Shopify, Salesforce, and more. No custom coding required.
12
Dashboard Analytics
Monitor geocoding request volume, success rates, and error breakdowns directly in the PostGrid developer console.
Benefits of Geocoding API
Eliminate Coordinate Errors
Geocoding unverified addresses generates inaccurate coordinates. PostGrid validates every address against USPS and Canada Post records before converting to lat/lng, ensuring your data is precise and reliable.
Optimize Routing and Delivery
Feed verified geocodes into your routing engine to reduce delivery time, cut fuel costs, and improve last-mile efficiency. Pinpoint-accurate coordinates mean fewer failed deliveries and driver detours.
Location Analytics
Map your customer base geographically, identify regional demand patterns, and build data-driven territory strategies using verified coordinate data appended to your CRM records.
Enrich Your Database at Scale
Append latitude and longitude to any volume of existing address records through bulk geocoding with NCOA validation, ensuring every coordinate reflects the most current, deliverable address on file.
Support Global Operations
Standardize and geocode addresses from 245+ countries and territories within a single API. A consistent coordinate format simplifies international expansion and cross-border logistical planning.
Geocoding API Use Cases
Last-Mile Delivery Optimization
- Capture exact latitudinal and longitudinal data to optimize routing and reduce transit time
- Differentiate between residential and business addresses to assign appropriate delivery windows
- Detect missing suite or unit numbers before dispatch to prevent failed delivery attempts
Customer & Territory Mapping
- Visualize customer distribution geographically to identify regional demand clusters
- Assign sales territories and field service zones based on verified coordinate boundaries
- Track location-based performance metrics across regions, zip codes, and countries
Real-Time Address Geocoding in Forms
- Geocode customer addresses at checkout or intake to capture coordinates at the point of entry
- Verify and standardize address input before assigning coordinates to prevent dirty data
- Populate lat/long fields automatically in your CRM, ERP, or logistics platform
Database Enrichment & Cleansing
- Add geocodes to existing address records in bulk to enable location-based queries
- Cross-check all addresses against USPS NCOA data to flag outdated or undeliverable entries
- Ensure global consistency by standardizing address formats across 245+ countries and territories before geocoding

Frequently Asked Questions
What is a Geocoding API, and How Does It Work?
A geocoding API converts a mailing address into latitude and longitude coordinates. PostGrid verifies and standardizes every address against USPS and Canada Post records before returning coordinates, so that the location data always reflects a real, deliverable address.
What is the Difference Between Geocoding and Reverse Geocoding?
Geocoding converts an address into coordinates. Reverse geocoding does the opposite, taking a latitude and longitude and returning the closest matching readable address. PostGrid supports both within the same verified address infrastructure.
How Accurate are PostGrid's Geocoding Results Compared to Google Maps API?
Google Maps geocodes against map data, which can return coordinates for non-deliverable locations. PostGrid only geocodes addresses verified against USPS CASS and Canada Post SERP records, which ensures that every coordinate corresponds to an address the post office confirms as deliverable.
Does PostGrid's Geocoding API Work for International Addresses?
Yes. PostGrid supports geocoding across 245+ countries and territories, standardizing every address to the destination country's postal format before returning coordinates.
How Does PostGrid's Geocoding API Pricing Compare to Google Maps API?
Google Maps charges separately for geocoding, address validation, and map usage. PostGrid bundles geocoding directly into the address verification request as one additional lookup, making it more cost-effective for businesses already verifying addresses at scale.
