Talk:Delivery point

From Wikipedia, the free encyclopedia

[edit] DP vs. DPB

You say "delivery point (also abbreviated DPB)". Say where the B comes from. --jidanni

It stands for Delivery Point Barcode. Since these digit generally do not appear in human-readable form in the address, they are almost exclusively associated with the POSTNET barcode in the US. Froese 18:51, 30 January 2006 (UTC)

In regards to the USPS, it is commonly abbreviated as DPBC. I don't believe I have seen it abbreviated to just DPB. Kenrus 21:45, 28 March 2006 (UTC)

[edit] Delivery points

Does every address in the country have a zip+4?Audejoos 22:33, 20 December 2006 (UTC)

Yes, definitely, every postal address in the United States (and trust territories served by the USPS) has a Zip+4. In fact, every address has a unique delivery point barcode (Zip+4+delivery point.) However, when coding a mailing list, there is often 3%-5% of records that can't be match—usually because of non-standard addresses. Froese 03:05, 21 December 2006 (UTC)

Say, Froese, can you point me somewhere to verify that? I suspected that to be the case, but it's really important for a project I'm working on to be sure that each DP is unique (beyond the uncodable ones of course :D). Thanks! True Vox (talk) 17:09, 29 February 2008 (UTC)
