Invoice Title / Tax Number Validator – Standardize Title, Format Address/VD/VKN (E-Invoice Compatible)

Invoice Title / Tax Number Validator Tool What Is It?

Where do most mistakes occur when issuing an invoice? Title, address, and tax number… Even a letter/space error can cause issues on the e-invoice/e-archive side. Invoice Title / Tax Number Validator Template solves this problem on a “single screen”: it performs title standardization, applies tax number validation, and automates address standardization and tax office formatting (VD). As a result, you get a invoice template that you can copy and paste.

What does this tool provide you?

• Title validator: Converts the company name into “invoice language” (invoice title validation, company title editing).
• Tax number check:
  • For the company vkn validation / vkn check
  • For individuals tckn validation (optional) This section meets the need for “tax number validation / tax number check / tax identification number validation.”
• Address/VD/VKN formats:
  • invoice address editing and neighborhood street no format, province district format, postal code format
  • tax office formatting (standard writing of VD)
• Output template: A invoice information template that can be copied as a single block like “title address vkn template.”

How do you use it? (short flow)

1. Paste the raw information of the company: Title, VD, VKN, address, city/district, postal code.
2. The tool cleans automatically:
   • automatic space correction, uppercase conversion (TR character compatible), punctuation correction
   • abbreviation standards (like Mah., Sk., Cd., No:)
3. Validation works: vkn validation (and if necessary tckn validation) gives the result “valid/invalid”.
4. Produces the template: A block of invoice issuance information appears on the screen that can be used for e-invoice/e-archive.

Output format (template logic)

The tool organizes the fields one by one and gives you a standardized output:

• Title: cleaned and standardized
• VD: in a single format
• VKN/TCKN: masked/clean
• Address: line arrangement, city/district/postal code in the correct place This significantly reduces the need for current account standard and accounting data cleaning.

To add on (Tools1984 makes a difference)

• Input mask + data validation: Prevent errors while the User is entering (VKN 10 digits, TCKN 11 digits, etc.).
• Corporate fields: mersis no, trade registry no, kep address validation, email validation, phone formatting, even iban formatting (the “company card” standard on the same screen).
• E-invoice technical compliance: naming output fields according to ubl-tr compliance logic and making them “ready for XML” (xml compliance).

Summary: You paste the raw company information; the tool performs title standardization, applies tax number validation (VKN/TCKN), formats address/VD/VKN, and produces a directly usable invoice information template.
