GCNA's free business network: contacts that keep themselves up to date

GCNA · 29 October 2026

Business contacts go out of date the moment someone changes jobs, phone numbers or offices. GCNA's free business network keeps them current: you share your card once, and every change reaches your connections by itself.

In short

Free for everyone in business: a personal account, a digital business card with QR code, connections and update emails.
When you change your card, every connection gets the new details by email with a vCard; in Odoo the linked contact updates automatically.
Your organisation is identified by your email domain, and your colleagues are mapped to it free of charge.
Only enterprise features for organisations and AI agents are charged, per user or agent and month, as the price list states.

What is the GCNA business network?

GCNA stands for Global Communication Network Alliance, an alliance of trusted service providers working on the platform of the same name at gcn-alliance.com. The business network is its free basic service: every member has a business card, and members who know each other are connected. A connection means you always have each other's current details.

How does a connection start?

There are two ways today:

An invitation after a call. In GCNA's Odoo Phone System you send your contact info to the person you just spoke with. GCNA emails your card with a vCard attachment and an accept link; replies go to you. The recipient opens the link, sees who invites them, enters name and company and accepts the terms. GCNA creates a free account if they have none, and you are connected.
A scan of your QR code. At a trade show or an event, someone scans the code on your phone or your printed card. They can save your contact as a vCard or connect: they enter their own details, confirm their email address, and you receive their card.

Invitations that nobody accepts are deleted after 30 days. The secret in an accept link sits in the part of the address that browsers never send to a server, and GCNA keeps only a keyed hash of it.

What happens when someone changes their details?

You edit your card at app.gcn-alliance.com: name, role, company, business email, up to four phone numbers, website, address, photo and company logo. When you save it, every connection receives an email with the new details and a fresh vCard. Their changes reach you the same way. If you use GCNA's Odoo Phone System, the linked Odoo contact takes over the new details automatically, so your CRM stays current without anyone typing.

What does it cost?

The business network is free of charge. That covers registering as a personal user, your digital business card with QR code, connections, update emails and the mapping to your organisation. Enterprise features for organisations and the registration of AI agents are charged per user or agent and month, as the price list states.

How does GCNA know which organisation I belong to?

By your email domain. Colleagues with an address at the same domain are mapped to the same organisation from the beginning, free of charge. A free-mail address such as Gmail or GMX is accepted together with your organisation's website, which must show that address; the website's domain then identifies the organisation. The email domain is the preferred way, and connections based on a website or a free-mail address may need additional approval before they are cleared to use GCNA.

Who sees my card?

Your connections see your card. The page behind your QR code shows only what you marked as public, and you can replace the QR code at any time, which retires the old one. GCNA stores card details encrypted. The privacy notice and the terms describe the details.

When you save your card, GCNA emails every connection the new details with a vCard. In GCNA's Odoo Phone System, the linked Odoo contact is updated automatically.
