Field guide

What each field on this site means and where the data comes from.

RDI（Residential / Commercial）

RDI (Residential Delivery Indicator) is a USPS flag that classifies an address as residential or commercial for delivery. Our RDI data comes from the Smarty address verification API.

Note: different suites in the same building can return different results. We read the full address, including the suite number, from each provider's location page and verify the complete address.

CMRA (Yes / No)

CMRA stands for Commercial Mail Receiving Agency. CMRA = Yes means the address is a registered mail-receiving business such as a UPS Store or mail center. Data from Smarty.

Mailbox number range

Anytime Mailbox lets you pick a mailbox number at sign-up. We record the lowest and highest available numbers, a rough hint of how busy a location is. Other providers do not publish numbers.

Photos / map

"Photos" opens the address in Google Maps, where you can see business photos and switch to Street View to check the storefront and surroundings.

Same address at other providers

Some locations work with several virtual mailbox providers. We detect the same address automatically so you can compare prices.

Data updates

Data is collected daily from each provider's public pages. New, removed and price-changed locations are all recorded.
