Organisations no longer need to submit a Public Services Network (PSN) Code of Interconnection Annex A spreadsheet when applying for connectivity accreditation, you’ll just need to check a box when you complete your application to confirm you meet the obligations. We’ve published guidance on how to apply for a PSN or GCN connectivity service compliance certificate, which you can find on the PSN website

Use this spreadsheet if you're a commercial supplier that wants to renew or get a PSN connectivity compliance certificate.
