About Address Verification System (AVS) checks

When making online purchases, you may be required to enter a billing address at checkout. This address may be used by merchants for payment verification purposes, including Address Verification Service (AVS) checks.

AVS is a fraud-prevention check used by merchants to compare the billing address you enter (usually the numeric values including the street number and zip code) with the address on file for your card. If they do not match, the transaction may be declined.

Declined purchases due to an "Address verification failed" error

If your purchases are declining with the reason "Address verification failed", "billing address mistmatch" or "AVC check failed", please ensure you're entering the correct billing address for your specific Halocard. If the problem persists, try entering the zip code 00917 at checkout (the default ZIP code from Halocard's issuing bank) which often resolves AVS-related issues.
