Batch requests for administrative units

There are two ways in which UID services wishing to introduce the UID to their data bases can match their data with that of the UID register:

Detailed information on the content/character of Input and Output files can be found under "Additional information". Please note the differences in the Output files depending on whether the matching is direct or indirect.

How the UID batch requests work

Data is matched (directly or indirectly) using an automated similarity search and we advise users to check whether the UID entities proposed by us actually correspond to the units for which they were looking.

The Jaro-Winkler score as well as the given search result (e.g. “NameAddress”) are good indicators of the quality of results. Results based not only on the name but also on the address are more reliable.
