Request Network Code

Login Required

In order to request a network code, or changes to one, you must be logged in to the system. In addition, only users associated with an existing network (either as the originator of the request that created it, or identified as a principal investigator) may submit changes. If you are responsible for a network and are not currently associated with it, you can request a change by emailing us.

Permanent Networks

Permanent networks should:

  • expect to operate continuously for the foreseeable future,
  • have a relatively stable set of stations and instruments, and
  • distribute data in the FDSN SEED format.

Temporary Networks

Short-term deployments, active source experiments, or networks that produce non-SEED (eg. SEGY) data should request a temporary network code.
