One Shilajit product can have several laboratory numbers without anything being wrong. A document may show a report number, sample ID, order or job reference, certificate number, batch, revision and test-request number.
The question is not why there are two numbers. It is what each number identifies, and whether the records connect clearly to the product being sold.
The Short Answer
Two report numbers do not automatically mean conflicting COAs or a false document. Trace the product, batch, submitted sample, laboratory record and any later revision. Separate tests, separate laboratories and revised reports can all create multiple identifiers for legitimate reasons.
Why One Product Can Have Multiple Laboratory Numbers
A product may be tested by different laboratories, submitted more than once, or assessed for separate parameters. Each activity can generate its own records.
Some numbers track the laboratory’s order; others identify a sample or the issued report. A revision may add another reference. A certificate and a report may also have distinct identifiers, depending on the issuer’s system.
Read the field labels before comparing the numbers. Two different kinds of reference are not two competing answers to the same question.
Report Number vs Sample ID
A report number identifies a laboratory document or report record. A sample ID identifies the submitted sample within the laboratory’s system. They are not interchangeable.
If marketing calls a sample ID the “report number,” the linked document may still be relevant, but the terminology needs clarification. Compare the labelled fields rather than looking for the same digits anywhere on the page.
Batch/Lot Number Is Different Again
A batch or lot number is a production or tracking reference, not the laboratory document’s identity. Several reports may relate to one batch, and one report may contain separately identified sample entries.
A batch match helps establish the product relationship. It does not, on its own, tell you whether two reports describe the same submission, separate tests or a revision.
Order, Job and Certificate Numbers
Laboratories may use an order or job number to organise work alongside their sample and report references. A test-request number may identify the requested work rather than the finished document.
Certificate numbering also varies. Some issuers use “certificate” for the analytical document; others attach a separate certificate reference. Follow the document’s terminology and ask the issuer about unclear fields.
Multiple references can coexist on a valid record. Their roles matter more than their quantity.
Revision vs Separate Test
A revised report may retain its original number, add a version suffix or use another identifier. A separate test is a different activity, not automatically a correction to the first report.
Check issue dates, revision notes and any wording saying the document replaces or supersedes an earlier version. A later date alone does not establish a retest, and a changed suffix alone does not establish a revision.
Where the relationship is unclear, request the current document and an explanation of what changed. Keep the earlier reference so the history remains traceable.
Two Laboratories Can Produce Two Different Report Numbers
Different laboratories use their own numbering systems. A Eurofins report number need not resemble an Anresco order number or a Bureau Veritas reference.
Compare the laboratory, sample, batch, dates and test scope together. There is no sound “one product, one report number” rule.
When Multiple Numbers Need More Explanation
Ask for clarification when the same claimed test is attached to unexplained report numbers, when sample linkage is unclear, or when one document appears to supersede another.
A marketing reference that differs from the linked PDF also needs checking. It could be a labelling mistake, an outdated link or a different document; establish which before drawing a conclusion.
Dates and scope should fit the stated relationship. An unresolved mismatch calls for document tracing, not an automatic fraud allegation.
How Buyers Can Trace Document Lineage
Product → Batch/Lot → Submitted Sample → Laboratory → Order/Job → Report → Revision/Certificate
Use this as a tracing framework, following the labels actually present. Not every laboratory uses every field, and revision or certificate references apply only where relevant.
For each document, note which sample and batch it describes, which laboratory issued it, and whether it remains current or has been superseded. Keep separate submissions separate until evidence establishes their relationship.
Buyer Checklist
- Product/formulation: what the record describes.
- Batch/lot: the production reference and product connection.
- Laboratory: the issuer’s identity.
- Report number: the document reference as labelled.
- Sample ID: the submitted sample reference.
- Order/job: the work-order reference, if present.
- Certificate number: any separately labelled certificate reference.
- Dates: report issue and revision dates.
- Tests: the analytes and scope covered.
- Supersession: whether one document replaces another.
- Explanation: how the seller or laboratory connects the records.
Not every field appears on every report. Ask the issuer about missing or ambiguous references rather than filling in the gaps yourself.
What Does Not Prove a Problem
Two different report numbers, a report number beside a sample ID, or separate laboratories using different references are not evidence of falsification by themselves.
A revised document with a clear history can also be legitimate. What matters is whether the identifiers and document relationships can be followed.
What Would Be a Stronger Warning Sign?
Identifiers that cannot be reconciled, a linked document for another product or batch, unexplained alterations, missing laboratory identity or contradictory revision history deserve closer review.
Request the complete document and clarification from the seller or issuing laboratory. Until the mismatch is resolved, avoid treating that record as verified evidence for your product. The gap needs an explanation; it does not, by itself, establish fraud or a legal violation.
Golden Example: Multiple Identifiers Are Normal
Golden’s published records show several identifier types attached to two documented batches. Read each reference under its published label.
SLJT01LQ
- Eurofins Scientific: Report 4999802-0; Sample 15422471; Lot SLJT01LQ.
- Bureau Veritas: Report 1086405; Job/Sample AEDFL2213391-001; Batch SLJT01LQ.
HI-SHL-0226
- Eurofins Scientific: Report 5374116-0; Sample 16388887; Lot HI-SHL-0226.
- Anresco Laboratories: Order 960349; Sample 1352051; Batch HI-SHL-0226.
- TTI: Batch HI-SHL-0226.
Anresco’s order number is not relabelled as a report number. Bureau Veritas’s combined Job/Sample field remains described as published. Different laboratory systems serve different tracking purposes.
What These Golden Records Show
Multiple identifiers can coexist legitimately, while the batch reference provides a production link. Document type and submitted-sample identity still need to be read separately.
TTI remains batch-only in this example. No report, order or sample number is supplied where it has not been established in the reviewed published summary.
The records do not establish the batch currently being shipped. Nor do shared batch references alone prove that different laboratories received identical split samples.

Golden sells Shilajit and has a commercial interest in this discussion. The same document-tracing standard applies to our records as to any other seller’s.
Frequently Asked Questions
Why can one product have two lab report numbers?
Separate laboratories, tests, submissions or revisions may generate different records. Check each document’s scope and relationship to the product.
Is a sample ID the same as a report number?
No. A sample ID identifies a submitted sample; a report number identifies the laboratory document or report record.
Is a batch number the same as a COA number?
No. A batch number is a production or tracking reference. A COA number identifies an analytical document under the issuer’s system.
Can two labs issue different reports for the same batch?
Yes. Each laboratory uses its own identifiers. Match the batch and examine the sample and test scope separately.
Does a revised COA need a new number?
Identifier practices vary. Check the version, date and revision or supersession notes rather than assuming a new number is required.
When should multiple report numbers concern a buyer?
When their relationship cannot be explained, the product or batch does not match, or the revision history conflicts. Seek issuer clarification before relying on the records.
How can I verify which report belongs to my product?
Trace the product and batch to the submitted sample and laboratory document. Check its scope, dates and current revision status with the seller or issuer where necessary.
