1.1 Workflow description

Title
Verify a phone number with uProc
Workflow name
Verify a phone number with uProc

Do you want to avoid communication problems when launching phone calls?

This workflow verifies landline and mobile phone numbers using the uProc Get Parsed and validated phone tool with worldwide coverage.

You need to add your credentials (Email and API Key - real -) located at Integration section to n8n.

Node "Create Phone Item" can be replaced by any other supported service with phone values, like databases (MySQL, Postgres), or Typeform.

The "uProc" node returns the next fields per every parsed and validated phone number:

  • country_prefix: contains the international country phone prefix number.
  • country_code: contains the 2-digit ISO country code of the phone number.
  • local_number: contains the phone number without international prefix.
  • formatted: contains a formatted version of the phone number, according to country detected.
  • valid: detects if the phone number has a valid format and prefix.
  • type: the phone number type (mobile, landline, or something else).

"If" node checks if the phone number is valid.

You can use the result to mark invalid phone numbers in your database or discard them from future telemarketing campaigns.

  2. 2. Import the template into n8n

    Open n8n, import the downloaded JSON, and review each node before activating the workflow.

  3. 3. Configure credentials and variables

    Replace placeholder credentials, API keys, webhook URLs, account IDs, and environment-specific values with your own settings.

  4. 4. Test with sample data

    Run the workflow manually or in a staging workspace, inspect node output, and confirm downstream systems receive the expected data.

  5. 5. Activate and monitor

    Enable the workflow only after testing, then monitor executions, errors, and rate limits during the first production runs.

5. General Notes & Resources

Review imported nodes carefully before activation. This catalog entry is intended to help you inspect the workflow structure, understand required services, and find related templates faster.

Node names, credentials, schedules, webhook paths, and external service limits may need adjustment for your workspace.
