About

PAV (Postal Address Verification) is a CASS Certified™ API that allows you to standardize, correct, and validate U.S. and Canadian addresses in one step. Save time, money, and resources by verifying that addresses are deliverable before mailings or packages are sent out. PAV helps businesses ensure data quality for U.S. and Canadian customers. When verifying a Canadian address, the API will only verify the city, state, and ZIP Code. The province name must be abbreviated in order for PAV to append a missing ZIP Code to a verified Canadian address. CDYNE offers trial license keys for all web services so that you may test the APIs for free. Postal Address Verification (PAV) is an API (Application Programming Interface). The API allows a business's IT department to configure the Web Service on a web page, application, or database with a few lines of code. There is no software to buy or install, no complex system to learn, and the service's data is automatically updated each month.

About

Postcoder is an API from Allies Computing that gives developers a single endpoint for verifying and validating customer contact data at the point of entry. Used across sectors from healthcare to retail, it's built to drop into checkout, onboarding, and account creation flows with minimal friction. What's included: Address lookup – Postcode, partial address, or coordinate-based search across Royal Mail PAF, Ordnance Survey AddressBase, and 249 countries worldwide. Bank validation – Real-time sort code and account number verification, with branch data and direct debit eligibility returned in the response. Email validation – Domain and formatting checks with disposable address detection. Mobile validation – Live network status checks across 200+ countries. OTP verification – SMS-based one-time password delivery. Clear documentation, multi-language sample code, and a straightforward REST structure mean integration is quick. 30 day free trial with no credit card required.
