Projects per Space, numbers per Project, Verified IDs per Project, Call backlog, or Message backlog - product:signalwire_space # Request an increase to your SignalWire Space limits When a SignalWire Space has reached its [default limits](#default_limits), SignalWire Support is able to increase them on a case-by-case basis per our customers needs. :::info Trial Mode These limits apply to SignalWire Spaces **not in Trial mode**. New accounts remain in Trial mode until at least $5 USD of credit is added. Consult the [Trial Mode](/guides/trial-mode) guide for more information. ::: ## Default limits {#default_limits} You can find the **Default Limits** for each SignalWire Space below. | Space limit | Default | | : | :-- | | Number of Projects | Unlimited | | Phone numbers per Project | 1000 | | Verified IDs | 1000 | | Call backlog | 10,000 | | Message backlog | 10,000 | Refer to the [Rate Limits](/guides/numbers-api/getting-started/signalwire-rate-limits.mdx) guide for more information on queueing and backlogs for Calls and Messages. ## Request increased limits Request an increase to your Spaces default limits by filling out the [SignalWire Space Increase Request Form](https://support.signalwire.com/hc/en-us/requests/new?ticket_form_id=30642768121499) and submitting the required form and necessary documentation to start the account verification process. SignalWire’s Space Compliance team reviews submissions to approve or deny the request. They will then notify the submitting user of the results or request additional information to approve. ### Phone number limits If you need more than 1000 phone numbers in a single project, the request must be approved by our team of Account Executives. Please be prepared to share detailed information about your use case. :::caution Auto top-up required If approved, you **MUST** set up auto top up on your project to the total cost of the numbers monthly **before the limit will be raised**. This requirement prevents the suspension of services due to insufficient balance. Pricing for phone numbers can be found on the [SignalWire pricing page](https://signalwire.com/pricing/messaging). :::
