About imei number code
Where to Find IMEI Number Code Suppliers?
China remains the central hub for mobile device manufacturing, with key supplier clusters concentrated in Shenzhen, Zhongshan, and Chengdu. These regions host vertically integrated supply chains that support both original equipment manufacturing (OEM) and secondary market distribution of smartphones featuring unique IMEI identifiers. Shenzhen's electronics ecosystem offers rapid prototyping and high-volume production capabilities, while Zhongshan specializes in refurbished and used mobile phones compliant with international reconditioning standards. Chengdu has emerged as a center for 5G-enabled devices and eSIM-integrated models, leveraging regional incentives for e-commerce exporters.
Suppliers across these hubs provide scalable solutions ranging from bulk OEM orders to drop-shipment of individual units. The proximity of component suppliers, testing facilities, and logistics networks enables lead times as short as 7–15 days for ready-to-ship inventory. Buyers benefit from diversified offerings including unlocked handsets, customizable firmware configurations, and IMEI-compliant devices suitable for global carrier networks. Production flexibility allows for MOQs starting from one unit for used devices to 3,000+ pieces for custom-branded smartphones.
How to Choose IMEI Number Code Suppliers?
Evaluating suppliers requires due diligence across technical compliance, production capacity, and transaction reliability:
Regulatory & Technical Compliance
Ensure all devices carry valid, non-duplicated IMEI numbers registered under GSMA standards. For export markets, verify compliance with FCC (USA), CE (Europe), or NTRA (Middle East) regulations where applicable. Avoid suppliers advertising "IMEI-changing" functionality unless explicitly intended for development or testing purposes, as such devices may be restricted in commercial resale.
Production and Customization Capability
Assess operational scale through the following indicators:
- Minimum factory output exceeding 5,000 units/month for sustained volume fulfillment
- In-house access to firmware programming, SIM lock configuration, and IMEI writing tools
- Customization options including branding, packaging, storage variants, and OS-level modifications
Cross-reference product listings with on-time delivery performance (target ≥96%) and response efficiency (ideally ≤2 hours).
Transaction and Quality Assurance
Prioritize suppliers with verifiable quality control processes, including pre-shipment testing of IMEI authenticity and network compatibility. Utilize secure payment methods with escrow protection, particularly when sourcing high-value or bulk shipments. Request sample units to validate build quality, boot sequence integrity, and IMEI consistency across software and hardware layers before placing full orders.

Performance Analysis
High-revenue suppliers like Shenzhen Songming and Shenzhen Jipstar demonstrate strong buyer retention and fast response cycles, ideal for repeat procurement. Chengdu Junchen stands out with perfect on-time delivery and access to next-generation 5G models, though lower reorder rates suggest limited post-sale engagement. Ying Tai Electronics offers large-scale OEM production at low per-unit costs but imposes high MOQs and slower communication. Zhongshan Gaoxin and Jipstar specialize in flexible, low-MOQ channels suited for small businesses and testing labs requiring single-unit acquisitions with valid IMEIs.
FAQs
How to verify IMEI authenticity from a supplier?
Request IMEI batch verification reports or use GSMA-approved tools like TAC checkers to confirm origin and uniqueness. Validate against online databases such as IMEI.info or official carrier unlock portals to ensure no blacklisting.
What is the typical lead time for IMEI-coded phone orders?
Ready-to-ship units can dispatch within 3–7 days. Custom OEM orders require 15–30 days depending on tooling and firmware setup. Air freight adds 5–10 days internationally; sea shipping takes 25–40 days.
Can suppliers provide IMEI-unlocked devices?
Yes, most suppliers offer factory-unlocked phones compatible with global carriers. Confirm that unlocking is performed via official firmware methods, not third-party software, to maintain warranty and update eligibility.
Are IMEI-changing phones legal to import?
No—devices with modifiable IMEIs often violate telecommunications laws in many countries, including the USA, EU nations, and India. Importing such devices may result in customs rejection or regulatory penalties. Procure only from suppliers providing fixed, GSMA-compliant IMEIs.
How to negotiate pricing and terms with suppliers?
Leverage order volume for discounts, especially above 3,000 units. For smaller buyers, emphasize long-term partnership potential. Always clarify warranty coverage, return policies, and whether firmware updates are supported post-purchase.
