Questions about changes to ZIP code databases

Questions about changes to ZIP code databases

 

We receive many questions about our ZIP Code Databases that pertain to the changes that occur to them. See below:

  • How often is your database updated?
  • What type of ZIP code information is updated?
  • How many changes are made to the database every month?
  • Do the changes in ZIP codes affect my business?
  • What ZIP code database subscription is right for me?


While the last two questions vary from business to business, many of these can be answered.

Our ZIP code databases come directly from the USPS every month. This data contains fresh, updated information that is up to date when compared with the USPS website’s own ZIP code lookup.

The number of changes from month to month typically vary between 1,000 to 2,000. From February to March, there were 1,327 differences found in the 5-digit ZIP code database, Commercial Edition! And even more changes occur in the ZIP+4 databases.  These changes vary on all aspects of our data from ZIP codes to city names. Many ZIP codes are added and subtracted every month.

These changes can significantly affect your business. Maillings and customer lookups can become complex and troublesome if you do not have an accurate, current ZIP code database.

Depending on your type of business, the cheapest solution would be to purchase the 1-year subscription. This entitles you to either quarterly or monthly updates for the next year. If your company requires 100% accurate ZIP codes, we recommend buying the monthly downloads. That way your CRM databases will help you maintain your customers and give you a competitive edge.
