OSM Street Name Warnings for LD Postal Area

Warnings for street names in OSM objects with postcodes in addr:postcode tags in the LD Postal Area, based on OSM data from 2024‑02‑23 18:12:30 Z. (The data comes from postcode checks that another tool does, so only includes OSM objects with valid postcodes.) Street names are taken from the following, in order of precedence: the addr:place tag, the addr:parentstreet tag, the addr:street tag, the name tag on street or associatedStreet relation if present, and the addr:locality tag. Remember that only OSM-compatible sources can be used to fix any issues flagged by this tool.

Street Name Mismatches

Each postcode unit normally only includes addresses on a single "street" (although there can be one or more "dependent streets" off a main street within a single unit). The table below lists OSM objects whose computed 'street name' differs from the dominant 'street name' for other objects in that unit. Such difference may be caused by typos in the street name, by objects having the wrong postcode, or by a dependent street being tagged as addr:street, without the main street being appropriately tagged. (In the latter case, I would recommend using addr:parentstreet for the main street, and addr:street for the dependent street. The main street will then be recorded in this tool, but data users unaware of the additional tag, will get something sensible from the addr:street tag.) Note that the 'Dominant Street' listed in the tables is just the most used on other OSM objects with the same postcode — it is not necessarily correct.

Partially Missing Street Names

OSM objects with an addr:postcode tag, with without a computed street name (see above for method), where at least one other OSM object with the same postcode has a street computed street name. If the postcodes are correct, then the object in question will normally have the same street in its address.

Fully Missing Street Names

OSM objects with an addr:postcode tag, with without a computed street name (see above for method), where none of the other OSM objects in the same postcode unit have a street name. In some postcode units, the addresses do not have streets, so the entries here are not necessarily errors.

Highways with Postcodes

OSM objects with an addr:postcode and a highway tag. It is debatable whether postcodes should be added to streets at all, but if they are to be, it might be preferable to use the postal_code tag instead, as the postcode on the street does not form part of an address.

No such streets found in this area.

Unexpected Punctuation

Street names containing a comma, colon, semi-colon, forward slash or backward slash, or a hyphen not between words. Occasionally such usage may be legitimate.
Regular expression: /([,:;\/\\]|^-| -|- |-$)/

Unexpected Numbers

Street names containing a number. Note that some street names legitimately contain road numbers (e.g. "A147") when the road does not have another name.
Regular expression: /[0-9]/

Capitalisation Issues

Street names starting with a lowercase letter, or having two consecutive uppercase letters.
Regular expression: /(^[a-z]|[A-Z][A-Z])/

No such streets found in this area.


Street names containing common suffix/descriptor abbreviations, which would normally be expected to be spelt out in full. Note that the abbreviation of 'Saint' to 'St' is often present in the official name of a street, so 'St' is not necessarily an error.
Regular expression: / (Ave|Blvd|Cl|Cresc?|Ct|Gdns?|Grvs?|Ln|Rd|Sq|St|N|S|E|W)(\.?,? |$)/

No such streets found in this area.

White Space Issues

Street names containing any white space characters other than spaces, two or more consecutive spaces, or starting or ending with a space.
Regular expression: /([\a\e\f\n\r\t]| |^ | $)/

No such streets found in this area.

Other Odd Characters

Street names containing anything other than letters, punctuation, spaces and numbers. Not all warnings here will be errors; some may be legitimate uses.
Regular expression: /[^A-Za-z0-9 '\.,:;()/\\-]/

No such streets found in this area.
