NCOALinkTM correct Spelling Errors in my names and addresses?
NCOALinkTM will not correct spelling errors in your names or addresses. Address Standardization will standardize your addresses to postal regulations and may also correct some street name misspellings. DSF2 also has the ability to correct misspelled street names. 24. Will NCOALinkTM tell me if an address is deliverable? NCOALinkTM will give you move update information and usually provides a ZIP + 4. DSF2 determines the deliverability of address records. ZIP + 4 validates addresses based on valid house number ranges but not the actual number. DSF2 validates based on exact house number and apartment number. 25. I processed my file through NCOALinkTM and have received returned mail pieces. Why didn’t NCOALinkTM catch these undeliverable addresses? It is estimated that only 66.9% of mail is deliverable as addressed. The remaining percentage has some form of addressing deficiency which could affect deliverability. Endorsed mail and First-Class Mail can be forwarded or returned to the mailer
