Frequently Asked Questions

Everything you need to know

What is the correct format for a US address?

A correct US address format includes the recipient's name, street address, city, state, and zip code. For example: John Doe, 123 Main St, New York, NY 10001.

Why is proper address formatting important?

Proper address formatting ensures that your mail and packages are delivered accurately and promptly. Incorrectly formatted addresses can lead to delays or lost mail.

Can I use this service for international addresses?

Yes, our service also provides formatting guidelines for international addresses to ensure your mail reaches its destination abroad.

Should I use periods in state abbreviations?

No, USPS prefers two-letter state abbreviations without periods (e.g., 'NY' not 'N.Y.'). This standardization helps automated mail sorting systems process addresses faster.

What's the difference between ZIP and ZIP+4 codes?

A standard ZIP code has 5 digits identifying a delivery area. ZIP+4 adds 4 more digits for more precise location identification, improving delivery accuracy and speed, though the 5-digit format is still acceptable.

How do I format an apartment or suite number?

Place apartment or suite numbers on the same line as the street address, after the street name. Use abbreviations like 'Apt 5' or 'Ste 200'. Alternatively, you can place it on a separate line above the street address.
