Audit the business truth first
Confirm the official name, customer-facing address rules, phone, website and hours before updating platforms. Document intentional variations such as department numbers.
Prioritize sources
Start with the platforms customers and data providers actually use, then consider reputable industry associations and locally meaningful sources.
Clean conflicts and duplicates
Old addresses, duplicate profiles and mismatched phone numbers can confuse customers. Remediation should be recorded so future updates do not recreate the issue.
Reviewed sources
Primary sources and standards
Use these official resources to confirm platform rules and technical guidance. They are maintained by their publishers and may change over time.
