# Addresses The buyer can query address availability. The buyer can search by postcode to get a list of locations which may be available to order to in that region or may look up a single address via UPRN ## Query Address Search - [POST /queryAddressSearch](https://ala-api.docs.cityfibre.com/openapi/addresses/queryaddresssearch.md): To check the availability of a given location, the buyer should send a request containing either a postcode or a UPRN. The seller is then going to respond with detailed information about the queried location. If the buyer queried using a UPRN, the response will contain only one location. On a postcode request, the seller might respond with multiple locations that match the given postcode. The location details include among other fields: UPRN, RFS (Ready For Service) status, cabinet release date, LOC (Limit Of Construction), if the order will be a preorder (aka \ XML tag is returned).
