I'm trying to print a label and postage and send something to Puerto Rico. Each time I type in the address given I get a validation error from USPS.GOV: "Invalid address" it says. Is there a special format the address has to be in for PR? I have never shipped to PR before.

I was unable to find an option so USPS does NOT validate the address, nor was the USPS help pages any help.

Thank you.

Try being a little less specific with the address.  (don't use an apartment number, don't use "street" or "lane")  That usually helps when I get an error.

Aha. So be less specific just so I can get a label printed, then hand write the rest of the address on?

In some latino countries, the streets are labeled "A", "B", or "C" and the houses "1", "2" or "3". So my address looks like: Calle A #33 which means "Street A house #33". Zip code validates fine using another tool on the USPS web site.

There is also an "urbanization" field, which the recipient said is "La Hacienda".

PR addresses are frequently tough to standardize. Try something like

A 33 URB LA HACIENDA

or, you might be able to get it to accept

33 CALLE A

and put LA HACIENDA in the c/o line.

I have another tool that I use for address standardization at work. It's a bit more flexible at figuring out various inputs and coming up with the right output than the usps site is. If you will PM me the address, I'll see if I can figure anything out for you.

If you are less specific, you may get a hit with either the USPS "correct" address or a choice of addresses (eg, if there are apartments for an address).   

Or try the zip minus the city or the city minus the zip.

Cathy, great info!  Thanks.
