Standardize US Phone Numbers with Multiple Format Options and Validation

## Workflow Overview: This n8n workflow template takes a US phone number as input, validates it, and returns it in multiple standard formats, including handling extensions. It's designed to streamline the process of standardizing phone number data within your automations. ## How it Works: **Input:** Accepts a phone number string as input. This number can be in various common formats (e.g., `(555) 123-4567`, `555.123.4567`, `+15551234567`, `5551234567x890`). **Formatting Removal:** Strips all non-numeric characters to isolate the core number and any potential extension. **Validation:** - **Country Code Check:** Verifies if the number starts with the US country code (`+1` or `1`) or assumes US if no country code is present and the length is correct. - **Length Check:** Ensures the main number component consists of exactly 10 digits after stripping formatting and the country code. **Output Generation (if valid):** If the number passes validation, the workflow outputs the phone number in several standardized formats: - **Number Only:** 5551234567 - **E.164 Standard:** +15551234567 - **National Standard:** (555) 123-4567 - **Full National Standard:** 1 (555) 123-4567 - **International Standard:** 00-1-555-123-4567 **Extension Handling:** If an extension is detected in the input, it is separated and provided as: - **Extension (Number):** 890 - **Extension (String):** 890 **Use Cases:** - Cleaning and standardizing phone number data in CRM systems. - Formatting numbers before sending SMS messages via APIs. - Validating user input from forms. - Ensuring consistent phone number representation across different applications.
