Need a DUNS number without spending your time working through unfamiliar requirements and correspondence? Crystal Tax helps companies prepare their information, submit the agreed application and deal with follow-up questions. Tell us your company’s country and the platform or partner requesting the number.
You entrust the agreed process to our company. We check the purpose and related requirements, flag inconsistencies before submission and explain the next steps. The service agreement sets out the work, responsibilities and how we coordinate with you.
We review the purpose, country and legal structure, check for an existing record, and compare names, addresses and registration details with your documents. This helps identify inconsistencies before they cause avoidable rework.
Within the agreed scope, we prepare the application, handle correspondence and help answer requests for clarification. You provide the underlying company information and confirmations that require your involvement; we explain what is needed at each stage.
D-U-N-S is a nine-digit Dun & Bradstreet identifier. Organisation account checks also depend on the company information and the platform’s requirements. Obtaining the number and approval of the account are separate steps.
If you already have an error message, send its exact text and any existing number. We will assess the specific issue instead of starting another application without checking the record.
You pay for professional assistance. We agree the work and fee before starting, based on the country, existing record, documents and corrections needed. Let us know your launch date so we can discuss timing for your case. External review remains with the reviewing organisation.
For an initial enquiry, provide the legal name, country, purpose and preferred deadline. For the work itself, we will agree the required company documents, address and contact details. Include any previous application or error message. The questionnaire above can be completed online or downloaded.
For US procurement requirements, see NCAGE application support. If the company has yet to be created, we can also discuss US company formation and accounting support.
Describe what you need and what has already been attempted. We will prepare a proposal with the scope, fee and responsibilities for the next steps.

Our advantages
Corporate structuring, company registration in Ukraine and abroad, tax and reporting, migration, bank accounts, DUNS and NCAGE codes. We run the whole project, from choosing the solution to the finished documents.
Confidentiality terms are set out in our contract. We do not pass information about a client or their project to third parties, except where the law expressly requires it.
We compare jurisdictions against your business task: tax regime, reporting, substance requirements and access to banking. On the call we go through the upsides and the limits of each option.
We name the timeline for every step before the work starts — it depends on the jurisdiction, the registrar and the bank. Personal data is used only to deliver the service.
We handle the correspondence with registrars, government bodies and banks and answer their requests ourselves. From you we need documents and signatures.
We take each case to the finish: if an authority or registrar comes back with remarks, we revise the documents at no extra charge. The fee is calculated for your task before work starts.
