How to fit a street address into the IRS 35-character limit

· 1 min read

The IRS says its EIN system allows 35 characters for street addresses and recommends standard USPS abbreviations. Preserve the street number and the apartment, unit or suite number needed for delivery. Abbreviate familiar street suffixes and unit designators first.

What to check

Use line 4 for mailing information. When a different street address is entered on line 5, use the physical address there, following the instructions for foreign addresses where applicable. Keep the full mailing address in your records and confirm with the recipient that the shortened version still routes correctly.

Example

For a U.S. mailing address, 100 West Harbor Boulevard Suite 408 can be shortened to 100 W Harbor Blvd STE 408. The building number and suite survive the abbreviation.

Before you proceed

  • Count the characters in the street address field.
  • Preserve the unit number and other routing information.
  • Use the foreign-address instructions when they apply.

Can I shorten the country name to make the address fit?

The SS-4 instructions say to spell out foreign country names. Shorten the street entry where appropriate and put the country in the applicable mailing or location field.
