University Domains Guide
Understanding how university domain verification works and how to manage domain lists.
Our university domain database contains thousands of verified educational institution domains from around the world. This guide explains how domain verification works, how our database is maintained, and how you can work with domain lists in your applications.
Domain Extraction
We extract the domain from the email address (everything after the @ symbol).
student@university.edu → university.edu
john.doe@mail.harvard.edu → mail.harvard.edu
Database Lookup
We check if the domain exists in our verified university database.
Regional Filtering
We apply any regional restrictions based on your target group settings.
Custom Domain Lists
We check against any custom domain allowlists in your target groups.

Regular Updates
Our domain database is updated regularly to ensure accuracy:
- Monthly updates from official educational directories
- Quarterly review of domain status and validity
- Real-time addition of newly verified domains
- Removal of expired or invalid domains
Missing Domains
If you encounter a legitimate university domain that's not in our database:
How to Report Missing Domains
- Verify the domain is actually used by the educational institution
- Check the institution's official website for confirmation
- Contact our support team with domain and institution details
- We'll review and add legitimate domains within 2-3 business days
Domain Status Monitoring
We continuously monitor domain status to maintain database quality:

Do
- • Use regional targeting for broad coverage
- • Create specific target groups for precise targeting
- • Cache domain validation results to improve performance
- • Monitor for new domains relevant to your use case
- • Report legitimate domains that are missing
Don't
- • Assume all .edu domains are valid (some are not educational)
- • Hardcode domain lists in your application
- • Rely solely on domain endings for validation
- • Include personal domains (gmail.com, yahoo.com) in target groups
- • Forget to handle subdomain variations
Issue: Student email uses subdomain not in database
Example: student.email@mail.university.edu where only university.edu is in database
Solution: Our system automatically checks parent domains. If mail.university.edu isn't found, we check university.edu.
Issue: International university not recognized
Example: University in developing country with limited online presence
Solution: Contact support with official documentation. We prioritize adding institutions with verified accreditation.
Issue: Too many false positives
Example: Targeting too broad a region includes unwanted institutions
Solution: Create more specific target groups with curated domain lists rather than relying solely on regional filtering.
