"Total postcodes collected" counts all postcodes collected on this site that haven't been subseqently deleted, excluding those from our partner site, freethepostcode.org.

"Prefixes collected" lists the number of unique prefixes (also known as "outwards" — the first half of a postcode collected), also excluding freethepostcode.org data.

"Prefixes liberated" gives a rough percentage estimate of the number of prefixes collected between both sites compared to the total in the country. This is probably an over-estimate.

"Sectors collected" lists the number of unique sectors (places with the same "outward" part, and the same first number of their "inward" part, such as "OX11 4AB" and "OX11 4TZ"), excluding freethepostcode.org data.

"Sectors liberated" gives a rough percentage estimate of the number of sectors collected between both sites compared to the total in the country. This is probably an over-estimate. (The total number for the country is taken from here.)

The Known missing prefixes page gives another measure of our progress, in terms of the prefixes/districts we know about, collected from a separate source.
