Colombia Check-MIG Errors and Problems – How to Fix Them 2026
Running into problems with the Colombia Check-MIG form is frustrating, especially when your flight is approaching. This troubleshooting guide covers the most common Check-MIG errors, why they happen, and exactly how to fix each one. The official portal is at apps.migracioncolombia.gov.co/check-mig.
For general information about the form, see our guide on what is Colombia Check-MIG.
Error 1 – Website Won’t Load or Is Very Slow
Causes: Server overload during busy travel periods, poor internet connection, outdated browser, or browser cache issues.
Solutions:
- Switch to a different browser (Chrome, Firefox, Safari, or Edge)
- Clear your browser cache and cookies, then reload
- Try incognito/private browsing mode
- Switch from Wi-Fi to mobile data (or vice versa)
- Disable VPN if you are using one – VPNs often cause portal issues
- Try from a different device (laptop instead of phone, or vice versa)
- Wait 30-60 minutes and try again if the server appears overloaded
Error 2 – Form Submission Fails
Solutions:
- Check all required fields are filled – look for red highlights or asterisk (*) fields
- Ensure your email address is correctly formatted (no spaces, proper domain)
- Verify passport expiry date is in the correct format (DD/MM/YYYY)
- Try a different browser
- Clear cookies and retry
- Check your internet connection is stable throughout the submission
Error 3 – Confirmation Email Not Received
Solutions:
- Check your spam or junk folder – government emails often end up there
- Wait 15-30 minutes – email delivery can be delayed
- Verify the email address you entered (look for .con instead of .com, missing dots, etc.)
- Add migracioncolombia.gov.co to your email whitelist
- Try resubmitting with a different email address (Gmail works reliably)
Error 4 – System Says “Too Early”
Check-MIG can only be submitted within the 24-hour window before your Colombia arrival time. If you are submitting more than 24 hours before arrival, the system will reject it. Wait until you are within that window. See our Check-MIG deadline guide for timing details.
Error 5 – Passport Number Not Accepted
Solutions:
- Double-check you are entering the passport number exactly as printed – every letter and number
- Do not add spaces, hyphens, or other characters unless they appear in the actual number
- Ensure you are entering the passport number, not any other ID number
- Some passports have letters at the beginning or end – include these
Error 6 – Flight Number Not Found
Solutions:
- Enter the flight number exactly as shown on your booking confirmation (e.g., “AV204” not “Avianca 204”)
- For codeshare flights, try both the marketing carrier and operating carrier numbers
- Verify against your actual booking confirmation document, not travel apps
Error 7 – Name Mismatch
Solutions:
- Enter your name exactly as it appears on your passport – including all given names and middle names
- Include all surname components if you have a compound last name
- Do not abbreviate – use the full names as in the passport
What If You Can’t Complete Check-MIG Before Your Flight?
- Screenshot any error messages as evidence
- Try completing it at the departure airport using airport Wi-Fi before check-in
- Inform airline check-in staff about the technical problem
- Some Colombian airports have assistance for on-arrival registration, though this is not guaranteed

Frequently Asked Questions
Can I resubmit Check-MIG if I made an error?
Yes. Submit a new Check-MIG with correct information. Colombian immigration will use your most recent valid submission. There is no penalty for resubmitting.
Why does Check-MIG keep timing out?
The portal experiences high traffic before major travel periods. Try during off-peak hours, use a different browser, or switch your internet connection. Disabling your VPN often resolves timeout issues.
What browser works best for Check-MIG?
Google Chrome is generally the most reliable browser for the Check-MIG portal. Firefox and Safari also work well. If one browser fails, always try another before giving up.
Can I complete Check-MIG at the airport?
Do not rely on this option – always complete Check-MIG before leaving for the airport. Some airports have assistance available, but it is not guaranteed and may cause significant delays.
