记名提单的英文为“straight bill of lading”，具体可见下文解释：

Straight bill of lading is a non-negotiable bill of lading. It is used where the goods have been paid for or do not require payment such as donations or gifts. Under this bill of lading, the shipping company will deliver the shipment to its consignee on presentation of identification. It is also called consignment bill of lading.

记名提单属于不可转让提单，在货物已付款或货物无需付款（比如，捐赠物或赠与物）的情况下使用。依据该等提单，一经收货人出示身份证明，航运公司即向收货人交付货物。

The bill of lading states that the goods are consigned to a specified person and it is not negotiable. A straight bill of lading is a document in which a seller agrees to use a specific transportation to ship goods to a certain location, and the bill is assigned to a specific party. The straight bill of lading details the type, quality, and quantity of the good. It also serves as the receipt upon arrival at the destination. Because it is assigned to a specific party, it is not negotiable and may not be re-assigned to another party.

记名提单会注明，货物交付予特定人士，不可转让。就记名提单而言，卖方同意使用特定运输工具将货物运送至特定地点，并且将提单分派给特定方。记名提单会注明货物类型、质量、数量。此外，记名提单也可以作为货物抵达目的港的收据。由于记名提单是分派给特定方的，记名提单不可转让，也不可以重新分派给另一方。

不记名提单的英文为“bearer bill of lading”，具体可见下文解释：

Bearer bill of lading states that delivery will be made to whosoever holds the bill. Such bill may be created explicitly or it is an order bill that fails to nominate the consignee whether in its original form or through an endorsement in blank. A bearer bill can be negotiated by physical delivery.

就不记名提单而言，货物可以发给持有提单的任何人。该等提单可以明确创建，也可以是未指定收货人的指示提单（无论是正本提单或是空白背书）。不记名提单可以实物交付的方式转让。

This document allows the goods to be delivered to the holder of it. It may also be an "Order bill of lading" without stating to whose specific order the bill, and delivery of cargo under it, are subject or it could be an "Order bill of lading" indorsed in blank that is without identifying to whom the cargo should be delivered.

不记名提单允许将货物交付予提单持有人；也可以是“指示提单”，可以不注明提单以及货物的交付需要遵照哪方的特定指令，抑或是空白背书，不指明货物的收货人。

至于记名提单与不记名提单的最大差异，应该在于是否可以转让。《中华人民共和国海商法》第七十九条规定：

提单的转让，依照下列规定执行：

（一）记名提单：不得转让；

（二）指示提单：经过记名背书或者空白背书转让；

（三）不记名提单：无需背书，即可转让。
