A prestigious business address is only half of a professional presence in Istanbul. The other half is how your company answers the phone. If clients, suppliers or authorities call your personal mobile — or a number that goes unanswered — the address loses much of its value. This guide explains how a virtual office phone number and secretarial service work in Istanbul, who they are for and what they cost at GBC.
What Is a Virtual Office Phone Number?
A virtual office phone number is a dedicated phone number assigned to your company as part of your virtual office package. You print it on your business cards, website and invoices alongside your business address. Calls to that number are answered in your company's name by a professional reception team, so callers reach a real person instead of voicemail.
For foreign companies and founders who are not in Turkey full time, this closes an important gap: your Turkish business has a local presence on paper and on the phone.
What Do Secretarial Services Include?
At GBC, the secretarial side of a virtual office covers:
- Call answering in your company's name by our reception team
- Mail and parcel handling: everything sent to your business address is received and managed for you
- Mail notifications through the GBC App, so you know when something arrives
- English support for foreign founders and investors
Combined with a legal business address, this lets you run a professional operation in Istanbul without renting a physical office.
Who Is It For?
- Foreign founders and investors setting up a company in Turkey who need both a legal address and a local point of contact
- International companies opening a Turkish branch before they hire local staff
- Consultants, agencies and freelancers who work remotely but want calls handled professionally
- E-commerce and online businesses that need a reachable company number for marketplaces, banks and customers
- Growing companies that want to separate business calls from personal phones
GBC Virtual Office Packages
GBC offers three virtual office packages. The phone number and call answering are included from the Plus package upwards. Prices are monthly and exclude VAT.
| Package | Monthly price | What's included |
|---|---|---|
| Address | 800 TRY | Legal business address, parcel tracking, mail notifications |
| Plus | 1,400 TRY | Everything in Address + dedicated phone number + call answering |
| Gold | 2,500 TRY | Everything in Plus + 3 coworking days, 3 meeting room hours and a secure locker every month |
Which one should you choose?
- If you only need a registered address and mail handling, Address is enough.
- If clients, partners or authorities will call your company, choose Plus — it's the package built for a professional phone presence.
- If you also meet clients in person every month, Gold adds workspace and meeting room hours, which often costs less than booking them separately.
Your Address Options
All three packages are available at three GBC locations. Each address can be used for company registration, the tax office and notary procedures.
| Location | Area |
|---|---|
| GBC Pol Center | Levent — Istanbul's central business district |
| GBC Duran İş Merkezi | Levent |
| GBC Beyoğlu İş Merkezi | Taksim, next to İstiklal Avenue |
Setting Up a Company in Turkey?
If you're forming a company, the business address is a formal requirement: it appears in your articles of association, the trade registry and your tax registration. Our guide on how to register a company with a virtual office in Istanbul walks through the process. For a full comparison of costs, see virtual office prices in Istanbul.
This article is for general information. Company formation and tax registration requirements depend on your company type; we recommend working with a local accountant (mali müşavir).
