SuiteLink
A USPS database that appends secondary address information (suite, floor, or department numbers) to business addresses that are missing this detail.
SuiteLink helps mailers add missing secondary address information to business addresses in multi-tenant buildings. When a business occupies a specific suite in an office building but the mailer's database only has the street address, SuiteLink can append the correct suite number based on the business name and building address.
The SuiteLink database is compiled from information provided by building managers and businesses to the USPS. It is accessed through CASS-certified software during address processing.
Adding suite information improves delivery accuracy and can convert a DPV 'missing secondary' result to a confirmed delivery point. SuiteLink processing is particularly valuable for B2B mailers whose address lists may lack secondary designators.
