How to Use This UUID v7 Parser

Using our UUID v7 parser is simple and fast:

Paste your UUID: Enter any UUID v7 in the input field above (with or without hyphens)
Parse instantly: Click "Parse UUID" or press Enter to decode the UUID
View details: See timestamp, components, and binary representation
Generate new UUIDs: Use the "Generate UUID v7" button to create new time-ordered identifiers

The parser accepts UUIDs in both formats: 018c7e69-6f4e-7abc-9def-0123456789ab or 018c7e696f4e7abc9def0123456789ab

What is UUID Version 7?

UUID v7 (Universally Unique Identifier version 7) is a time-ordered UUID format introduced in RFC 9562. It represents a significant improvement over previous UUID versions for database and distributed systems.

Key Features of UUID v7

Time-Ordered

Contains a Unix timestamp in milliseconds, making UUIDs naturally sortable by creation time.

Better Indexing

Sequential nature improves database B-tree index performance compared to random UUIDs.

Globally Unique

Combines timestamp with random data to ensure uniqueness across distributed systems.

Standard Format

Follows RFC 9562 standard with 128-bit structure compatible with existing UUID implementations.

UUID v7 Structure Breakdown

A UUID v7 consists of 128 bits organized as follows:

Timestamp (48 bits): Unix timestamp in milliseconds since epoch
Version (4 bits): Always set to 0111 (7) to indicate version 7
Random A (12 bits): Random data for additional uniqueness
Variant (2 bits): Set to 10 for RFC 4122 variant
Random B (62 bits): Additional random data for collision prevention

UUID v7 vs Other UUID Versions

UUID v7 vs UUID v4 (Random)

UUID v4: Completely random, poor database index performance, no time information
UUID v7: Time-ordered, excellent index performance, embedded timestamp

UUID v7 vs UUID v1 (Time-based)

UUID v1: Uses MAC address (privacy concerns), 100-nanosecond precision, non-sequential format
UUID v7: No MAC address, millisecond precision, naturally sortable format

When to Use UUID v7

Database primary keys requiring good indexing performance
Distributed systems where creation time matters
Applications needing sortable identifiers
Systems migrating from UUID v1 without MAC address exposure
Time-series data with unique identifiers

Common Use Cases for UUID v7

1. Database Primary Keys

UUID v7 makes excellent primary keys because the time-ordered nature reduces B-tree fragmentation and improves insert performance. Unlike random UUID v4, v7 UUIDs cluster together when created around the same time.

2. Distributed Event Logging

When logging events across multiple servers, UUID v7 allows you to sort events chronologically without requiring synchronized clocks or complex coordination.

3. API Request Identifiers

Track API requests with unique, time-ordered identifiers that make debugging and log analysis easier.

4. Document Management Systems

Assign UUID v7 identifiers to documents, ensuring both uniqueness and natural chronological ordering.

Frequently Asked Questions (FAQ)

What is UUID v7?

UUID v7 is a time-ordered universally unique identifier that includes a Unix timestamp in the first 48 bits, followed by version and random data. It provides better database indexing performance compared to random UUIDs while maintaining global uniqueness.

How do I use the UUID v7 parser?

Simply paste your UUID v7 into the input field and click "Parse UUID" or press Enter. The tool will display the timestamp, components, and binary representation. You can also generate a new UUID v7 using the "Generate UUID" button.

What information can I extract from a UUID v7?

You can extract the Unix timestamp (creation time), version number, variant type, and random data components. The tool displays both human-readable dates and binary representation of all UUID parts.

Can I parse UUIDs without hyphens?

Yes! Our parser accepts UUIDs in both formats: with hyphens (018c7e69-6f4e-7abc-9def-0123456789ab) or without (018c7e696f4e7abc9def0123456789ab).

What's the difference between UUID v7 and UUID v4?

UUID v4 is completely random with no time information and poor database indexing. UUID v7 is time-ordered with embedded timestamps, providing better performance in databases and natural sortability.

Is UUID v7 secure to use?

Yes, UUID v7 is secure for most applications. While it reveals creation time, it includes 74 bits of random data to prevent prediction and ensure uniqueness. It doesn't expose MAC addresses unlike UUID v1.

How accurate is the UUID v7 timestamp?

UUID v7 timestamps have millisecond precision based on Unix epoch time. The accuracy depends on the system clock when the UUID was generated.

Can I use UUID v7 as a database primary key?

Yes! UUID v7 is excellent for database primary keys because its time-ordered nature improves B-tree index performance and reduces fragmentation compared to random UUIDs.
