What is a Zip Code Lookup?

A zip code lookup is a search tool that helps you find the correct USPS 5-digit zip code for residential and business addresses across the USA. Some lookup tools can also help you find all the specific united states postal service zip codes for a particular city or state (ex. New York or California).

How can a Zip Code Lookup help me?

US Zip Code Lookups are extremely useful and can help in a variety of ways.

Sales

If you’re in a Sales position you know how important it is, to have quality, accurate sales leads. A lookup tool can help ensure that you have up-to-date postal street addresses with complete and accurate zip codes.

If you address your direct mailers with an inaccurate zip code, your mail will be returned to you by the post office because of an incomplete address. Returned mailers are a waste of money and all your precious time and effort. Before you mail your next direct mail campaign, be sure that your addresses include the correct code system / zip codes.

Recruiting

Recruiters need accurate postal mailing addresses in order to send recruitment messages and advertisements via direct mail. A lookup tool can help ensure that the addresses you’re using are up to date and accurate. This is important because you want to reach the right candidates the first time.

Friends/Colleagues

If you’re trying to send mail to a friend or colleague, but you’re unsure about their correct mailing address, a lookup tool can put your qualms at ease. Make sure you address your mail piece correctly, with the right zip cod, before you mail it.

How do I find all the zip codes for a City?

Although there are lots of Zip code Lookup tools out there, in most cases, you just need to know the correct spelling for the City you want to target, and the state that the City is in. After you enter the City name and State, the tool will display a list of all the five-digit zip codes that fall inside that City or State.

A ‘great’ zip code lookup tool should only provide you with accurate, valid USPS zip codes.

However, not all companies and websites are reliable. So, before you trust a particular website or zip code lookup tool, be sure to do your due diligence and understand where they are getting the information from.
