DSF is the most complete address database available and contains every deliverable address in the country. DSF can be used to obtain walk-sequence codes for postal discounts. DSF has no change of address information and will only tell you if a particular address is deliverable. No DSF address information is provided without reference to an existing address on a mailer's list. The prices shown above are the lowest price available for that price range.
Pricing is based on per thousand records processed.
The process is an exact matching process. Your record must match our database record exactly to get the DSF address information appended, otherwise no match will be given. Running some form of address verification is recommended before processing your list. Click here for instructions to upload your file via the Internet.
