  • What’s going on with my address? Never seen a problem like this.
    USPS isn't the only address validation. In fact, many businesses use Melissa. Check your address on USPS.com and also on melissa.com. If melissa doesn't have your address, you can submit a "suggestion" and hopefully they'll get that... Source: over 4 years ago
