Translation of Certificate of Social Security, Employment Record or Income (NSSI)

Certified translation of Bulgarian service and social-insurance income records

La Fit Trans prepares certified translations of certificates of employment or insurance service and social-insurance income, including records from the NSSI Insurance Archive. Personal details, employers, periods, positions, work category and income are reproduced accurately and consistently.

Separate certificates for service and social-insurance income

Certificates of insurance service, employment service and social-insurance income have different evidential functions. A service certificate records periods, positions, duration and, where applicable, the category of work. An income certificate records the amounts and periods used in pension or other social-security calculations.

NSSI may issue a certificate from documents deposited in its Insurance Archive by a terminated insurer with no legal successor. UP-13 and UP-15 records coexist with older UP-2 and UP-3 forms issued by employers or other competent bodies. The translation follows the actual document without merging those separate functions.

Periods, employers, positions, work category and income

Language control covers the insured person’s names and identifiers, the insurer’s name and legal succession, positions held, the start and end of every period, interruptions, working time, category of work and calculated service. Signatures, seals, outgoing reference, archive references and electronic validation features are included as visible source content.

For an income certificate, each year and month, currency, gross or insurable amount, column, subtotal, total and note concerning unavailable data is checked. Terminology is aligned across the file, particularly when the certificate accompanies an employment record book, payroll records, employer statements or pension correspondence.

Certified translation for pension and social-security proceedings

A certified translation may form part of a pension or benefit claim, recognition of insurance periods, proof of professional experience or an administrative review abroad. Intended use matters because one authority may request the full personal document while another relies on official exchange between competent social-security institutions.

Preparation includes extraction of tables, identification of legible authentication features, specialist translation, independent revision and final comparison with the source. Translation does not recalculate service or income and does not replace a pension authority’s decision; it accurately presents the data certified by the issuer.

Translation certification and authentication of the Bulgarian record

Certification of the translation concerns the translated document. An apostille, consular legalisation or other authentication of the Bulgarian source concerns its origin and signature. They are separate services determined by the destination, receiving body and the way in which the certificate was issued.

Within the European Union or under international social-security agreements, some information may be exchanged directly between institutions. That does not mean every personal or employer-issued record is accepted without translation. The actual route follows the written requirement of the specific body, without universal promises about apostille or exemption from authentication.

Price based on tables, periods and language pair

Price depends on the language pair, page count, table density, number of employers and periods, legibility, archive notes, turnaround and type of certified copy. A certificate covering one period differs substantially from a multi-page schedule containing monthly income, interruptions and attachments.

Translation, independent revision, certification, extra copies, source-document handling and delivery are calculated separately when required. The preliminary quotation reflects the actual structure and purpose of the record rather than applying one generic price to an undefined NSSI certificate.

Translation time for UP-2, UP-3, UP-13 and UP-15 records

Turnaround includes table preparation, translation, independent revision and verification of every period, employer, position, amount and total. A legible electronic record containing all pages can be processed more predictably than photographs with cropped columns, unclear seals or missing continuation sheets.

Issue of the certificate by NSSI, an employer or another authority is separate from translation. Apostille, subsequent legalisation, procurement of a duplicate and international delivery also have independent schedules and enter the overall timeline only when they form part of the order.

Remote assessment of the certificate and attachments

A legible PDF or clear images of every page allow identification of the certificate type, language, tables, periods, attachments and visible authentication. Non-essential personal data may be concealed for an initial assessment if the structure, issuer and volume remain identifiable.

One file may include the certificate, employment or insurance record book, employer statements, decisions, correspondence and forms from the foreign authority. Joint assessment keeps names, employers and insurance terms consistent. The original is needed only where a particular authentication or submission requirement calls for it.

ISO 17100 control of periods, income and insurance terminology

The translation follows a controlled ISO 17100 process with an appropriate translator, independent reviser and final verification. For service and income records, control concentrates on periods, units, work categories, positions, insurer names, numerical columns and the relationship between intermediate and final totals.

La Fit Trans coordinates language and administrative work online and through its office network. A larger pension file uses a shared terminology record so that the same person, employer, position and insurance period are not rendered inconsistently across separate documents.

Not an employment record book, tax note or European form

A service or income certificate is not an employment record book, personal-register extract, tax income note or pension award decision. Each record has its own issuer, contents and evidential role. Translation of one cannot create missing periods or replace the other evidence required by an authority.

Portable documents and structured electronic messages under European social-security coordination are also separate instruments. When a file includes U1, P5000, a letter from a foreign insurance body or a data form, the set is assessed together, while every item is translated according to its own structure.

Frequently Asked Questions

Are service and social-insurance income certificates the same?

No. A service record proves periods and duration, while an income record contains amounts for defined periods. They may be issued and submitted together but have different evidential functions.

What is the difference between UP-2, UP-3, UP-13 and UP-15?

UP-2 and UP-3 are familiar older forms for income and service. UP-13 and UP-15 occur among records issued from the NSSI Insurance Archive. Translation follows the exact title and contents of the document produced.

Does translation automatically recognise service abroad?

No. Translation presents the Bulgarian record. Recognition of periods, income and pension rights is decided by the competent Bulgarian or foreign institution.

Does an NSSI record always require an apostille?

No. The destination, authority, international rules and method of issue determine the requirement. Translation certification and source authentication are separate steps.

Is a scan sufficient for a preliminary quotation?

Yes. A legible file containing every page is normally sufficient to assess language, tables, volume, timing and possible authentication. The original may be needed at a later stage.

Certified translation for the particular pension or social-security file

The La Fit Trans quotation accounts for the certificate type, issuer, destination, receiving body, language, periods, tables, attachments, certification route and deadline. The completed translation presents service and income data clearly and consistently within the particular pension, social-security, employment or administrative file.
