An incorrect listing may originate from a completely different source from the website where you see it. Map services, business directories, social platforms and search engines copy data from one another or combine registers with user contributions.
Correcting it is therefore often a source investigation: where did the error originate, which party can actually change it and which derived systems then need to refresh?
First record where the error is visible and what the correct information should be. Then check whether the same error appears in other sources. If several services show exactly the same discrepancy, that can indicate a shared data source.
Correct the information as close to the primary source as possible and keep evidence of the change.
Because caches, indexes and derived databases do not all refresh at the same time. Some services fetch new data periodically; others have their own correction process. An old snippet can therefore remain even though the source page is already correct.
Check the source and the display separately and record the date on which the source was changed.
Not blindly. A claimed profile may already exist or a listing may be linked to an old account. New profiles can create duplicates. First try to establish whether existing access can be recovered and who currently manages it.
If access to the underlying account or domain is missing, also see the background on technical continuity if ongoing administration turns out to be needed after recovery.
Keep screenshots, URLs, the date, ticket or case number and the exact correction requested. This makes follow-up contact much easier and prevents having to rediscover later what has already been tried.
