1. EIN Section

Problem: Users can’t find their EIN or submit it incorrectly.

Solution:

  • Where to locate:

    • IRS-issued CP‑575 Notice (your EIN confirmation letter)

    • Business tax returns (1040 Schedule C or Form 1120S)

    • Bank or supplier accounts linked to your organization

    • Your accountant or tax preparer

  • How to format:

    • Always include the dash: 12‑3456789

    • No spaces or extra characters

  • If you still can’t find it:

    1. Visit the IRS EIN lookup tool or call the IRS Business & Specialty Tax Line.

    2. Use a tax professional to request a copy of your EIN notice.

    3. Once retrieved, enter it exactly as on official documents.

2. Website Errors

Problem: Application fails due to website URL problems during verification.

Why it matters:

Twilio requires a publicly accessible website — behind-the-scenes pages or password-protected forms are not supported .

Quick fixes:

  1. Use a main public URL (e.g. https://yourbusiness.com) — not private links.

  2. Ensure the site loads over HTTPS without redirects or login gates.

  3. Confirm your Privacy Policy and Terms are visible.

409 – Duplicate campaign

  • Meaning: You’ve previously submitted a campaign with the same details.

    • Fix Steps: Contact DripJobs Customer Help to Cancel or Modify your existing campaign.

400 – Missing required field

  • Meaning: One or more mandatory fields are blank or improperly formatted.

    • Fix Steps:

      1. Review form and ensure all fields are completed.

      2. Verify business registration, EIN, address, phone, and authorized rep info. 3. Correct formatting (e.g., dash in EIN).

      4. Click “Acknowledge & Continue” to revalidate.

4. Best Practices (to avoid issues)

  • Double‑check EIN format: Always include the dash.

  • Verify website: Include legal pages (Privacy, Terms) and ensure public access.

  • Use corporate email/phone for the Authorized Rep — avoid personal or free service addresses.

  • Provide accurate address/rep info — matches official documents like EIN registration.

  • Maintain logs/screenshots of submissions in case of disputes or rejections.
