UUID Information
A valid UUID must:
- Be 128 bits long (32 hexadecimal digits)
- Have canonical groups in 8–4–4–4–12 positions
- Have a valid version (1, 2, 3, 4, 5, 6, 7, or 8)
- Have a recognized UUID variant

What this tool helps you do
UUID verification checks textual structure and can identify version and variant bits. It can show that a value is well formed, but it cannot prove the identifier exists, belongs to a particular record, or was generated securely.
When it is useful
- Validating imported identifiers
- Checking an API parameter
- Inspecting UUID version metadata
- Normalizing identifiers before storage
A practical example
Validate an incoming value before converting it to a database UUID type. Then perform authorization and existence checks independently against application data.
Limitations and common mistakes
Accepting a syntactically valid UUID must not bypass access control. Braces, URN prefixes, whitespace, and noncanonical forms may require an explicit normalization policy.
Frequently asked questions
Can a valid UUID still be wrong?
Yes. Syntax validation says nothing about whether it identifies the intended object.
Does uppercase change a UUID?
No. Hexadecimal case does not change the underlying 128-bit value.
