UUID v4 is generated using random numbers, making each UUID completely unique with no embedded information. UUID v7 embeds a Unix timestamp in the first 48 bits, making them sortable by creation time while still being unique. UUID v7 is preferred for database primary keys because of its time-ordered nature.
Yes. UUID v4 uses 122 random bits, making the probability of a collision astronomically low (about 1 in 2^122). For practical purposes, every UUID generated is guaranteed to be unique across all systems worldwide.
Yes. Use the bulk generation feature to generate up to 100 UUIDs at once. You can choose between v4 and v7, select uppercase or lowercase format, and copy all generated UUIDs with a single click.
