Got an admit card that says “iON Digital Zone” or “IDZ” on it and no idea where exactly that is? You’re not alone. Every year, lakhs of candidates appearing for SSC, banking, railway, UPSC, and private recruitment exams Google this same thing the night before their test.
Here’s the problem: search for your specific IDZ centre online, and you’ll find three different addresses on three different websites — sometimes even for the same building. This guide fixes that. Every address below has been cross-checked against official facilitation-centre lists, so you’re not relying on a five-year-old blog post that never got updated.
What Is TCS iON Digital Zone (IDZ)?
TCS iON Digital Zone is a network of computer-based exam centres run by Tata Consultancy Services (TCS) under its iON business unit — the same TCS that builds enterprise software, but this arm focuses purely on running large-scale digital assessments. When a bank, a state government, or a university needs to test lakhs of candidates across dozens of cities on the same day, TCS iON is usually the machinery behind it.
These centres conduct exams for:
- Banking (IBPS, SBI, RBI recruitment)
- SSC (CGL, CHSL, and other tiers)
- Railway (RRB, NTPC, Group D)
- UPSC and state PSC exams
- NEET / JEE and other entrance tests
- Private company recruitment drives (including TCS’s own hiring)
Each city can have multiple IDZ branches — numbered (IDZ 1, IDZ 2) or named after the locality (Omaxe City, Harahuwa Chauraha). This is exactly where most of the confusion starts.
Why IDZ Addresses Look “Wrong” Online — And How to Avoid a Mix-Up
Before the location list, one important heads-up: don’t trust the first address you find. Here’s why.
- Same building, different listing services. For Noida Sector 62 alone, you’ll see the address written as “B-36,” “C30/7A,” and “C-26” across different sites — these are simply different ways local directories have logged the same building over the years (near BHA Millennium Road, Sector 62, Noida — landmark: Samsung research centre).
- Confusing names. “IDZ Azad Puram” sounds like it could be near Delhi’s Azadpur — it’s actually in Lucknow, not Meerut or Delhi. Always match the city on your admit card, not just the branch name.
- IDZ 1 and IDZ 2 are often the same building. In Noida Sector 62, both wings sit in the same six-storey structure — different floors or entry gates, not different locations.
Golden rule: always cross-check the address on Google Maps against the exact wording printed on your own admit card before you leave home — conducting bodies sometimes shift candidates between nearby branches at the last minute.
Verified IDZ Locations & Addresses
1. IDZ 1 & IDZ 2 — Sector 62, Noida
- Address: iON Digital Zone (IDZ 1 & IDZ 2), C30/7A, BHA Millennium Road, C Block, Phase 2, Industrial Area, Sector 62, Noida, Uttar Pradesh – 201309
- Nearest Metro: Noida Sector 62 (Blue Line) — about 1 km, roughly 10–15 minutes by e-rickshaw or on foot
- Landmark: Near the Samsung Research Centre and Barclays office
- Note: IDZ 1 and IDZ 2 are wings of the same six-storey building — don’t panic if your friend’s admit card says a different number.
2. IDZ Omaxe City — Lucknow
- Address: SS Compuage, Omaxe Avenue, Omaxe City, Bijnor Road, near Baba Saheb Bhimrao Ambedkar University, Lucknow, Uttar Pradesh – 226025
- Getting there: Best reached via Lucknow–Kanpur Road; city buses and shared autos run to Bijnor Mod from central Lucknow.
- Candidate feedback: Located inside a well-maintained township with parking, basic food points, and a green, secure campus.
3. IDZ Harahuwa Chauraha — Varanasi
- Address: S R Platinum English School, Harahuwa Chauraha, Panchkoshi Marg, Varanasi, Uttar Pradesh – 221105
- Note: Tucked slightly off the main road near a flyover with several small shops nearby — use Google Maps rather than asking for “Harahuwa” alone, as the exact turn is easy to miss.
- Candidate feedback: Reports of the hall being non-AC, so dress accordingly and confirm on your admit card.
4. IDZ Powai — Mumbai
- Address: Aurum IT Park, Saki Vihar Road, near Ramada Hotel, Morarji Nagar, Powai, Mumbai, Maharashtra – 400087
- Nearest stations: Kanjurmarg (~6 km, BEST bus or auto) or Sakinaka Metro via Andheri (~8.5 km)
- Tip: This is a genuine IT park building — enter via the main Saki Vihar Road gate, not through the residential Powai lanes.
5. IDZ Kovilambakkam — Chennai
- Address: Fortune Towers, 1st & 2nd Floor, SH 109, 200 Feet Thoraipakkam–Pallavaram Radial Road, near Eachangadu Signal, Kovilambakkam, Chennai, Tamil Nadu – 600117
- Note: This is the centre most people mean by “IDZ Chennai” in search — Chennai also has a separate, smaller IDZ Kundrathur branch, so double-check your admit card’s exact address.
6. IDZ Coimbatore II
- Address: Prisdham Technologies, Akshaya Institute of Management Studies, No. 209/1B, Premier Nagar, Othakkalmandapam, Coimbatore, Tamil Nadu – 641032
- Candidate feedback: No food stalls right at the venue — carry snacks and water, and allow extra time as it’s roughly 20 km from Gandhipuram bus stand.
7. IDZ Chikalthana — Chhatrapati Sambhaji Nagar (Aurangabad)
- Address: E-50, beside CTR Manufacturing Industries Ltd, near Chikalthana MIDC Police Station, MIDC Industrial Area, Chikalthana, Chhatrapati Sambhaji Nagar, Maharashtra – 431006
- Note: Located inside the MIDC industrial belt — auto drivers know it by “Chikalthana MIDC,” not by “IDZ.”
8. IDZ Azad Puram — Lucknow (not Meerut)
- Address: Azad Technical Campus, Bangla Bazar Road, adjacent to CRPF Camp, Azad Puram, Bijnor, Lucknow, Uttar Pradesh – 226002
- Common mistake: Candidates often assume this is in Meerut because of the name similarity to other UP centres — it’s firmly in Lucknow’s Bijnor area, about 8 km from Charbagh Railway Station.
Exam Day Checklist: What to Carry (and What to Leave at Home)
Getting the address right is half the battle. Getting turned away at the gate over a document is the other risk. Here’s what candidates across IDZ centres consistently report:
- ✅ Printed admit card — a photo on your phone is not accepted
- ✅ Original government photo ID — Aadhaar, PAN, voter ID, passport, or driving licence (photocopies are not valid)
- ✅ Passport-size photograph, only if your specific exam notification asks for one
- ✅ Two HB pencils, if your exam requires rough work (check your specific instructions)
- ❌ Mobile phones, smartwatches, and other electronics
- ❌ Bags, wallets with excess items, and metal objects
- ❌ Any digital or photocopied ID — must be the physical original
Timing tip: Reach at least 45–60 minutes before your reporting slot. Entry is strictly time-slot based at most IDZ centres, and gates do close on the dot — arriving even a minute late has cost candidates their exam in past cycles.
Frequently Asked Questions
Is TCS iON Digital Zone the same as TCS (the IT company)?
Yes and no. It’s a business unit of Tata Consultancy Services, but it operates independently to run exams and assessments — it’s not connected to TCS’s software or client work.
Are IDZ 1 and IDZ 2 always different locations?
Not usually. In most cities (like Noida Sector 62 and Ramtekdi, Pune), the numbers refer to different floors or gates of the same building, not separate addresses.
What if the address on my admit card doesn’t match what I find online?
Trust your admit card first. Online listings (including this guide) can lag behind changes TCS iON makes to a centre. If in doubt, call the number printed on your admit card the day before your exam.
Is there a locker or bag deposit facility at IDZ centres?
Most centres offer some form of storage for bags and phones, but it isn’t guaranteed everywhere and can be paid. The safest approach is to carry only what’s mandatory and leave everything else at home or with someone waiting outside.
Can I use a digital copy of my ID on my phone?
No. TCS iON centres consistently reject digital or photocopied IDs — bring the original physical document.
Do I need to pay anything at the IDZ centre?
No. Your exam application fee (paid to the recruiting body) already covers your centre allocation. TCS iON does not charge candidates separately at the venue.
Centre addresses and facilities can change. Always verify the exact venue printed on your own admit card and, where possible, confirm with the conducting body a day before your exam.
