New Businesses are acquired from specialized research firms who collect and aggregate New Business records from a wide variety of sources. AtoZdatabases uses multiple providers to ensure coverage of real, operating businesses around the U.S. Key to the AtoZdatabases process is intelligent filtering to remove non-operating shell companies or "fake" businesses which are just additional telephone connections, rather than a unique business location. New Businesses are updated in AtoZdatabases on a weekly basis.

New Movers and New Homeowners are acquired through multiple sources including register of deeds records, new phone connects, utility connections, and self-reported information from websites offering services to those moving. When one purchases a new home, the transaction is recorded at the local county register of deeds' office. In the majority of states, these records are made available to the general public and are obtained and incorporated into the database. New phone and utility connection information is provided by those companies whenever a new connection is made. On average, records in the New Mover / New Homeowner file have been in their homes for 3 to 12 weeks when they first appear in the New Mover & New Homeowner database, with most being in their new residence between 30 and 60 days.

Government sources report their data on different schedules. Some counties provide the information every week, some counties report once a month, and some counties report whenever it is most convenient for them. This can result in a wide range of purchase dates being made available in each week?s data load, as well as fluctuations in counts from week to week.

Records in the New Mover / New Homeowner file have not been sourced using the USPS National Change of Address (NCOA) product. License agreements with the US Postal Service prohibit the use of NCOA in any way to create a new mover database.
